African Clawed Frogs (Xenopus laevis) are a popular choice for amphibian enthusiasts, especially beginners, due to their hardiness and ease of care. Understanding their dietary needs is crucial for ensuring their health and well-being in captivity. These frogs are native to southern Africa but have become invasive in the US, Chile, and Great Britain. They are fully aquatic freshwater frogs, meaning they require aquariums filled to the proper level needed for your filtration system. It is key to not use small pebbles for substrate, as African Clawed Frogs will consume them and become impacted, usually leading to death.
Natural Diet and Feeding Habits
In their natural habitat, African clawed frogs are opportunistic carnivores. Their diet consists of a variety of invertebrates and small vertebrates. As members of the Pipidae family, they lack a tongue, which means they use their front limbs to push food into their mouths. Their lateral line system, highly sensitive to vibrations, aids in detecting both predators and prey in murky water.
Nutritional Needs in Captivity
Providing a diverse and balanced diet is essential for maintaining the health of African Clawed Frogs in captivity. These frogs are carnivorous, requiring whole animal prey to meet their nutritional needs.
Variety is Key
A mixed diet is recommended to ensure your frog thrives. This can include comets, rosies, feeder goldfish, earthworms, crickets, and bloodworms.
Feeding Schedule
The frequency and amount of food should be adjusted based on the frog's age and size.

- Juveniles: Should be fed around 4 live crickets, a pinch of blood worms, 3 small earthworms, or a combination every other day. 1-2 Small Comets or Rosies can be fed every 3 days.
- Adults: Can be fed larger meals less frequently. With larger food like comets, rosies, feeder goldfish, and large earthworms, feed 3-4 items twice a week. With smaller food including crickets and bloodworms, feed 10 crickets or 3 pinches of blood worms every other day.
Food Options
- Live Foods:
- Crickets: A staple food, especially for younger frogs. To feed live crickets, use tongs to place them underwater.
- Earthworms: A favorite among African Clawed Frogs. Drop them in the tank and allow the frogs to hunt them down.
- Bloodworms: A nutritious option, especially for variety.
- Comets and Rosies: Small feeder fish that provide essential nutrients.
- Feeder Goldfish: Offer variety, but should not be the sole food source.
- Commercial Diets:
- Tetra Reptomin: An appropriate commercial diet that can be part of the rotation.
Practical Feeding Tips
- Size Matters: Ensure food items are appropriately sized to prevent choking or difficulty swallowing. These frogs will eat anything that fits in their mouth, and this can include smaller tank mates. Ensure your frogs are relatively the same size when housed together.
- Observe Feeding Behavior: Monitor your frogs during feeding to ensure they are eating properly and to adjust the amount of food accordingly. It is a lot of fun watching them gobble them down!
- Supplements: While a varied diet should provide most necessary nutrients, consult with a veterinarian or reptile expert to determine if any supplements are needed.
Enclosure and Environmental Considerations
The enclosure plays a significant role in the frog's ability to feed and thrive.
Aquarium Setup
- Space: An important feature for African Clawed Frogs is a large space to allow them to bolt around their tank.
- Substrate: It is key to not use small pebbles for substrate. African Clawed Frogs will consume them and become impacted, usually leading to death. Placing a layer of Fluval Plant and Shrimp Stratum promotes plant growth and can be passed through the frog if ingested.
- Plants: A variety of live plants will add cover and good nutrients to your enclosure. Java Moss, Java Fern, and Hornwort have flourished in enclosures with African Clawed Frogs.
- Decor: After placing around 2 inches of stratum on the bottom of the enclosure, you may add a piece of aquarium-safe driftwood. The goal is to cover as much substrate as possible, locking plants' roots in, and providing a natural environment. Be sure all stones are secure and will not move with a current. You may add other aquarium decor or driftwood once the base is complete!
- Filtration: A filtration system is needed for African Clawed frogs unless you pursue a bioactive aquarium. If using tap water, water conditioner must be used to remove harmful chemicals.
- Water Temperature: 65-75 degrees F (18-24 degrees C). A heat source is typically not needed because they thrive at room temperature.
Water Quality
Dirty water will make your frog sick. It is recommended to change the water every week, but it’s easier to use a low-flow aquarium filter. If you are using a low-flow aquarium filter, you can perform partial water changes every two weeks.
Common Feeding Challenges and Solutions
Refusal to Eat
- Possible Causes: Stress, illness, poor water quality, or an unvaried diet.
- Solutions: Check water parameters, consult a veterinarian, and diversify the diet.
Regurgitation
- Possible Causes: Overfeeding, food items too large, or illness.
- Solutions: Reduce portion sizes, offer smaller food items, and consult a veterinarian.
Obesity
- Possible Causes: Overfeeding, lack of exercise.
- Solutions: Reduce feeding frequency and increase tank size to encourage activity.
Additional Considerations
- UVB Lighting: Although African clawed frogs are aquatic, they are still active during the day, and UVB wavelengths travel quite well through clear water. For best results, use a bulb about half the length of the enclosure and housed in a fixture with a reflector. We recommend lighting to be on 8-12 hours per day, depending on the time of year.
- Handling: It is not recommended to handle your frog.
- Tank Mates: We do not recommend cohabitating African clawed frogs, as this species is known to have cannibalistic tendencies. However, it can be done if you are familiar with the species, the frogs are about the same size, and you are prepared for what is necessary to keep more than one together.
